Project description:White bass (Morone chrysops) are a popular sportfish throughout the southern United States, and one parent of the commercially successful hybrid striped bass (M. chrysops x M. saxatilis). Currently, white bass are cultured using diets formulated for other carnivorous fish, such as largemouth bass (Micropterus salmoides) or hybrid striped bass and contain a significant percentage of marine fish meal. Since there are no studies regarding the utilization of alternative proteins in this species, we evaluated global gene expression of white bass fed diets in which fish meal was partially or totally replaced by various combinations of soybean meal, poultry by-product meal, canola meal, soy protein concentrate, wheat gluten, or a commercial protein blend (Pro-Cision). Significant differential expressed genes and gene ontology of pairwise comparisons between control diet and each test diet are presented and discussed.
Project description:This study was conducted to investigate the effects of the rapeseed meal (RM) on two strains of gibel carp (A strain and F strain) and to explore whether two strains show the different molecular mechanisms to the fishmeal (FM) and rapeseed meal (RM). Transcriptomic analysis showed that amino acid metabolism, lipid metabolism and digestive system were three main biological processes affected by RM diet in both strains. The differentially expressed genes between strains were involved in amino acid metabolism, immune responses and lipid metabolism.
Project description:The purpose of this study was to investigate the effects of high levels of Tenebrio molitor dietary inclusion (15%) on molecular mechanisms that influence poultry health in a broiler chicken diet.
Project description:In the present study a 44k oligonucleotide salmonid microarray, qPCR and histology were used to investigate transcriptomic responses in the distal intestine during the first week of oral exposure to soybean meal in order to gain insight into early molecular response mechanisms. Intestinal tissue samples were taken on day one, two, three, five and seven after introduction of a soybean-containing diet and compared to a control group fed fishmeal. Day 1, day 2, day 3, day 5 and day 7 (n=10 per condition) post-soybean meal feeding Atlantic salmon hybridized to common reference and compared against control (day 0 of SBM feeding). Tissue = distal intestine.
Project description:The F5 generation of a wild-caught population of zebrafish (Danio rerio) from Mymensingh, Bangladesh, were used in this study. Replicate experiments were carried out with adult male fish aged 9 months. Each group was maintained in a 50L tank at 27M-11.5M-:C and 12:12h dark:light photoperiod and fed bloodworms (Ocean NutritionM-^Y, Belgium) to satiety for one week. The experimental protocol involved fasting fish for 7 days and subsequent refeeding a single meal of bloodworms delivered over a 3h period, after which any uneaten food was removed from the tank. Seven fish were sampled at -156, -24, 0 (prior to the meal), 0.75, 3, 6, 7.5, 9, 11, 24, 36h and killed humanely by an overdose of ethyl 3-aminobenzoate methanesulfonate salt (MS-222). Six samples from the 0, 3, and 6h time-points were used in the microarray hybridization.
